Mllll l l .ma Nl ATTORNEY Patented July 16, 1946 UNITED STATES PATENT OFFICE This invention relates to dispensers for liquid soap, face cream, tooth paste and the like; the main objects being to provide a dispenser of this type arranged so that the contents may be dispensed in desired quantities7 one having means to prevent residue material from adhering to and hardening on and about the discharge end of the dispenser and which retains the material immune from contamination and one which may be easily and quickly recharged. The dispenser possesses other features of advantage, some of which, together with the foregoing, will be specifically set forth in the detailed description hereto annexed. It is to be understood that the invention is not to be limited to the speciiic form thereof herein shown and described as various other embodiments thereof may be employed within the scope of the appended claims.

Referring to the drawings:

Figure 11 is a side elevation of a modied form of the spout.

Figure 12 is a top plan View, partly broken away, of the dispenser shown in Figure 1 to illustrate the cross-sectional shape of the receptacle of the dispenser. f

Referring particularly to the numerals of reference on the drawings, the dispenser comprises a base l from which a bracket 2 projects horizontally, said bracket being arranged for detachable supporting engagement With a Wall or other vertical surface in any suitable or conventional manner.

Formed in the upper portion of the base is a tapped socket or recess 3, tapped to receive the correspondingly threaded lower open end 4 of an 5 Claims. (Cl. 222-390) upstanding material receptacle 5 of oval ory noncircular form in cross section, shown in Figure 12, and preferably of glass or suitable transparent plastic.

A piston E is slidably but non-turnably disposed in the receptacle, and is threaded on a tubular piston rod At its upper endV the rod is open and terminates short of the top of the receptacle. Below the receptacle, the rod is journaled in the base I and projects with a threaded extension 8 some distance below the base. Depending from said extension is a reduced portion 9, from which in turn a reduced nozzle I0 dependss said nozzle terminating in a taper portion II and having a lateral opening I2 above the taper communicating with the hollow interior of the piston rod.

A collar I3 on the rod is counter-sunk in the top of the base,.while another collar I4 is secured on the rod extension just below the base. A sleeve-like spout I5 is threaded on rod extension 8 and surrounds the nozzle and the taper II, being formed at its lower end with a correspondingly tapered orice I, forming a ground valve seat. The spout is spaced from the oriced portion of the nozzle at all times, but orice I6 forms a leak-proof t with taper II when the spout is screwed up against the collar I4.

Said collar I4 is formed with an arcuate slot I1 of substantially semicircular extent, a pin It upstanding from the spout riding in said slot.

The spout may have vertical ribs or utes on its upper portion to facilitate turning, as shown in Figures 1 and 8 and formed with a concave taper, or it may be substantially cup shaped, as shown at I5-a in Figure 11 and have relativen7 deep Vertical recesses in its upper portion, as shown at I9 in Figure 10.

In operation, assuming that the receptacle is a prelled replaceable and initially capped member, the cap is rst removed and the receptacle screwed into the base, the latter being removed from the wall and inverted, if necessary, to prevent dropping of the material from the receptacle While the latter is being mounted. Before the receptacle is screwed onto the base, the piston is retracted on rod 1 to a, point adjacent the base. To dispense material from the receptacle, the spout is first turned in a direction to open the nozzle (or space taper I l from taper seat I6) as far as the collar slot I'l will permit. Further rotation of the spout in said direction then rotates the collar I4 and piston rod as a unit, causing the piston to rise in the receptacle and force material therefrom into the tubular rod at its upper end, and thence down the rod and out through opening I2 and past the nozzle and spout.

Residue or excess material issuing from the nozzle has a tendency to cling on the outside and become contaminated. To obviate this undesirable condition, the spout, after a dispensing movement, is turned to close seat I6 against nozzle taper II. This not only seals the material outlet I2 against contact with the air, but presents a smooth lower surface on the lower end of the spout which may be easily and quickly wiped clean of all material which may be adhered thereto.

Having thus described my invention in detail, What I claim as new and desire to secure b-y Letters Patent is:

1. A dispenser of the character described having in combination a supporting member provided with a socket portion having an axial bore therein, a container removably mounted in said socket, a tubular rod having an end portion thereof rotatively mounted in said bore, said end portion having a reduced threaded extension provided with a discharge orifice at its extremity, the other end of said rod being in communication with the interior of said container, an internally threaded stop collar removably engaging the threaded reduced extension of said rod, means for preventing relative rotation of said rod and said collar, a feeding member located Within the j container and having threaded engagement with said rod, and means for imparting rotating movements to said collar, so as to correspondingly rotate said rod and thereby impart axial movekments to said feeding member.

2. A dispenser of the character described having in combination a supporting member provided with a socket portion having an axial bore therein, a container removably mounted in said socket, a tubular rod having an end portion thereof rotatively mounted in said bore, said end portion having a discharge orifice therein at its extremity, theother end of said rod being in communication With the interior of said container, a stop collar detachably but non-rotatively secured to the rotatively mounted end portion of said rod at a position outside of said support, a feeding member located Within the container and having threaded engagement with said` rod, a closure for said discharge orifice rotatively mounted on said rod, and means coupling said closure With said collar, so that rotation of the closure will impart rotative movements to the co1- lar and corresponding movements to said rod and thereby impart axial movement to said feeding member.

3. A dispenser of the character described having in combination a supporting member provided With a socket portion having an axial bore therein, a container removably mounted in said socket, a tubular rod having an end portion thereof rotatively mounted in said bore, said end portion having a discharge orifice therein at its extremity, the other end of said rod being in communication with the interior of said container, a stop collar detachably but non-rotatively secured to the rotatively mounted end portion of said rod at a position outside of said support, a feeding member located Within the container and having threaded engagement with said rod, a closure for said discharge orifice rotatively mounted on said rod, and means coupling said closure With said collar, so that rotation of the closure will impart rotative movements to the collar and corresponding movements to said rod and thereby impart axial movement to said feeding member, said coupling means including means providing of limited relative rotation of said closure with respect to said collar.

4. A dispenser of the character described having in combination a supporting member provided with a socket portion having an axial bore therein, a container removably mounted in said socket, a tubular rod having an end portion thereof rotatively` mounted in said bore, a feeding member located Within the container and having threaded engagement with said rod, said end portion having a discharge orice therein at its extremity, the other end of said rod being in communication with the interior of said container, a sto-p collar detachably but non-rotatively secured to the rotatively mounted end portion of said rod at a position outside of said support, a closure for said discharge opening having threaded engagement with the reduced threaded extension of said rod, and means coupling said closure with said collar, so that rotation of the closure will impart rotative movements to the collar and corresponding movements to said rod and thereby impart axial movement to said feeding member, y
